3 Claims. (Cl. 256-13.1)

This invention relates to guard rails and more particularly to guardrails used on highways and parkways to prevent motorists from skiddinginto ditches, gullies and other hazards.

An object of the invention is to provide a guard rail structure whichmay be stamped out of sheet metal and assembled economically and whichwill have suflicient strength to withstand the impact of a skiddingvehicle or one out of control.

A further object is to provide a guard rail which will provide a surfacewhich is relatively uninterrupted so that a vehicle colliding with it atan angle will slide along the rail without hitting any obstruction whichwould cause a sudden stop and increase damage.

A further object is to provide a rail in which the posts supporting therails are covered so that any impact is borne by the rails themselvesand not by the posts.

A still further object is to provide a guard rail construction in whichthe rails themselves are not weakened by cutout portions, both holes orother perforations.

Briey, I provide a structure wherein the posts are made of sheet metalwhich may be cut ont in the at and stamped to provide rail recessingslots and thereafter formed on a forming brake into the desiredrectangular shape and welded to an anchor plate and provided with a top.The slots are so formed that after the post has been shaped the railsmay be inserted and welded into place.

Other objects and advantages of my construction will be apparent fromthe accompanying drawing and following description, in whichof Fig. 4but showing such view through a complete post.v

Referring more particularly to the drawings, the roadway or parkway isprovided with a curb in which is set .l anchor bolts 11 which arethreaded at the top and provided with a nut 12. My improved guard railis made in sections 15 Vand preferably consists of three post members2,733,897 Patented Feb. 7, 1956 16, 17 and 18 each of which is providedwith a base plate 19 through which the anchor bolts extend to fasten thesection in place. Each of the posts is provided with a series of slots20 in which a flat plate rail 21 is inserted. Normally, three rails 21,22 and 23 are used, but it is obvious that the number of rails isoptional and may Vary as desired. The rails 20 are disposed at an angleto the perpendicular axis of the post so that the flexibility thereofmay be brought into play should a vehicle collide with the guard rail.

In manufacture the posts 17 are cut out of sheet metal in the llat withthe slots 20 being cut on the face 25 and the sides 26 and 27. Thecutout blank is then formed on a forming brake into a rectangular shapeand welded at 28. The post itself is welded to the base plate 19 asshown at 29 and a top or cap 30 is then welded at 31 and 32 to the sidesof the post. The rails are then put into position in the slots 20 andwelded as shown at 33 and 34 so as to firmly position them in the slots.The entire unit 15 is then in condition to be anchored to the curb 10 bymeans of the anchor bolts 11 and the nuts 12. Each unit 15 is soconstructed that the ends 35 of the rails are spaced a short distanceapart to allow for contraction and expansion and to allow insuicientspace for a vehicle to be caught therebetween.

While I have shown in Fig. l three sections in place in a straight line,it will be appreciated that they may be placed at a slight angle to takecare of curves in the road.

I claim: Y

l. A guard rail comprising a plurality of rectangular posts havingfront, side and back faces, a plurality of slots in each of said postsextending through the front and partially through the side faces, saidslots being at an angle to the base of said posts, a plurality of flatrails positioned in said slots, a portion of said rails extending beyondthe front face of said posts.

2. A guard rail section including a plurality of hollowv rectangularposts each of said posts having a plurality of angular slots therein anda plurality of hat rails positioned in said slots positioned with theedges of said rails extending beyond the face of said posts.

3. A guard rail section including a plurality of hollow rectangularposts, a base plate on each post, each of said posts having a pluralityof angular slots therein and a plurality of flat rails positioned insaid slots at an angle to the horizontal with a substantial portion ofsaid rails extending beyond the face of said posts.
